    I’ve tried the following to clear all selection from a TreeList:

    tlConfig.SelectedItems.Clear()

     

    Nothing was removed from the selected collection. I then used the brute force method and it works:

    For Each selectedItem As TreeListDataItem In tlConfig.SelectedItems

        selectedItem.Selected = False

    Next

     

    Am I missing something with the Clear() method?

    Thanks,
    Paul

    Hello Paul,

     In order to clear all selected items you should use the ClearSelectedItems method of the RadTreeList. The controls internally keeps the selected indexes of the items that is why clearing just the SelectedItems collection does not work. 

    All the best,
